Photoelectric rain gauge

1. Product Introduction of Photoelectric Rain Gauge

Photoelectric rain gauge is also called photoelectric rain gauge and optical rain sensor. Photoelectric rain gauge is a kind of rain gauge that adopts photoelectric principle to measure. The equipment is constructed with optical sensor, which can measure minute rainfall, hourly rainfall and daily rainfall. quantity. FT-G1 photoelectric rain gauge adopts three-channel narrow-band infrared detector and pure sinusoidal AC signal source, which has the advantages of high precision, strong anti-environmental light ability, maintenance-free, compatible with other optical sensors (light, ultraviolet radiation, total radiation), etc. Can be widely used in meteorology, agriculture, municipal, transportation and other industries. The sensor is designed with low power consumption and can be applied to unattended observation stations in the field.

2. Product Features of Photoelectric Rain Gauge
This optical rain sensor adopts pure sinusoidal infrared light source, built-in narrow-band filter, and the rain-sensing surface reaches 78 square centimeters. It can measure rainfall with high precision and is not affected by high-intensity sunlight and other light. The high-transmittance rain cover does not affect direct sunlight, and is compatible with other built-in optical sensors, such as light, total radiation, and UV sensors.

5. Precautions for photoelectric rain gauge
1. There is no shielding within a radius of 1 meter around the sensor level to avoid the impact of water droplets splashing.
2. Trees should be avoided above the sensor installation position, and tree shade should also be avoided in the inclined direction
3. In order to ensure measurement accuracy, the sensor should Keep it installed horizontally
